Pushing the Limit: Fukushima Fingerprint Isotope Found in Salmon from 2015

Complete results from 2015 biotic monitoring. New results are larger icons with bold/italic labels.

For the first time, the Fukushima fingerprint isotope, cesium-134 (134Cs; half-life ~ 2 years), has been detected at an extremely low level in a Canadian salmon by the InFORM project. The single sockeye salmon that tested positive was sampled from Okanagan Lake in the summer of 2015, according to scientists from the Radiation Protection Bureau at Health Canada, in cooperation with Fisheries and Oceans Canada and local First Nations.  The sample was one of a few (7 out of 156 total) individual fish that had trace levels of the longer lived  cesium-137 (137Cs) (30 yr half-life) that we reported on last winter. To determine if this trace 137Cs was from Fukushima or remnant from atmospheric weapons testing, InFORM reexamined these individual fish samples to see if extremely low levels of 134Cs may be present. The results of this extended analysis show that trace (0.07 Bq kg-1) levels of 134Cs were detected in one sample from Okanagan/Columbia River population. No 134Cs was detectable in the other samples. The observed levels remain well below the action level (1000 Bq kg-1) set by Health Canada guidelines

As we reported in the winter 2016 update, 7 individual fish (out of the 156 measured) from 2015 tested positive for low levels (<1 Bq kg-1) of cesium-137 (137Cs). With its ~30 year half-life, 137Cs is still present in the environment from 20th century atmospheric weapons testing and Chernobyl in addition to the Fukushima accident.  In contrast, no individual fish from the 2014 monitoring effort were found to contain detectable levels of 137Cs. This difference led the team at the Radiation Protection Bureau to conduct a more detailed investigation of some of those few positive samples to determine if 134Cs, the Fukushima fingerprint isotope, was present. Results from 5 of those 7 are now available and discussed below. The remaining two samples are still in processing.

Increased Strontium in Sardines since Fukushima Accident?

Dogs fed sardines show high Strontium levels

by Dr. Peter Dobias, DVM

Why you might want to cut out small fish from your dog’s diet

I have had two dog patients with severely elevated levels of the element strontium. The interesting part is that these two dogs were fed a high amount of sardines and I highly suspect that strontium is coming from this source.

Strontium acts in the body the same way as calcium and deposits in bones. Sardines and other small fish are eaten whole with the bones and that is why they are more likely a source of this toxic element.

The reason why I am concerned is that the radioactive isotope strontium 90 is a toxic carcinogen and it has been released in Japan’s Fukushima disaster.

Here is an example of the results:

As a veterinarian, I source from almost three decades of experience, but still I like to see the proof. Hair testing for minerals and toxic elements has been really helpful because it is highly accurate and shows what is happening in different groups of dogs.

In the course of many years of testing, I have learned that dogs who eat fish-based foods have elevated mercury levels and sardines appear to be the cause of increased strontium. Since the Fukushima nuclear accident strontium is continuously being released into the oceans and not much is being done to inform the general public.

Sadly, I have noticed that dogs who have epilepsy have higher than average levels of strontium and mercury, which made me recommend against feeding fish and sardines to dogs, despite their nutritional benefits. Fish is not what it used to be.
